 * __Medicine:__ Most of the time, heart valve replacements and blood vessels are made of polymers such as Dacron, Teflon and Polyurethane.
 * __Industry:__ Plastic is the main part of industry, basically everything is made of that. Some examples could be bottles, cups, claculators, etc.
 * __Sports:__ Due to contamination, swimwears are now being fabricated with plastic, recycled from plastic bottles. ([|www.surffanatics.com/cat/pro/325179/src/surf_yahoo_CA])

2nd Ionization Energy - 2352.6 kJ mol-1 3rd Ionization Energy - 4620.5 kJ mol-1 Once upon a time there was a family that was lost in the forest. This happened in winter so they were cold and they needed something to get warm. They had got with some matches and woods that they found in the forest, but when they make fire, a minutes later it was off. T heir son, who was a super-intelligent 10-year-old boy remembered that his chemistry teacher, Gerardo, told him that carbon was an extraordinary fuel that can maintain fire for a long period of time. He told this to his parents, and they began to search for it all over the forest. Finally his father found some of it hiden under land, so they had everything they needed to warm themselves. This fire last for hours so they could sleep well it it also helped them to be found by a helicopter and return home.
 * Carbon comes from the Latin word **Carbo**
 * Electronic Configuration: 1s²2s²2p²
 * Atomic Radius: 70 pm
 * Ionization Energy: 1st Ionization Energy - 1086.5 kJ mol -1
 * Electron Affinity: 121.55 kJ mol-1
 * Electronegativity (Paulin Scale): 2.55
 * Discoverer and first use: Carbon has been used since the ancient times, so there's no specific discoverer and no specific first use.
 * Carbon in Industry: Carbon (coal) is used as a fuel, and is the largest source of energy that is use for the generation of electricty in all the world.
 * Carbon in Society: With Carbon we can make graphite, that is use to make pencils, this helps people write so it has an important role not only in society but in the world.
 * I think that the economic impact of carbon is really big, because with carbon you can elaborate or fabricate some products that are useful for people such as graphite that, as I mention before, allows us to write, without that, paper won't be useful at least we shoul only use markers or pens.

Quantum Computing

Quantum computing is a different form of computing from the classic ones because it uses qubits instead of bits. Some problems that are unsolvable can then became solvable with this type of computing based in working with energy levels instead of electric ones. Quantum computing has a solid relationship with chemistry, because it can identify quantum mechanics such as the positions of electrons and the orientations of photons’ polarization. It also has an important relationship with technology, when the levels of the nanometers are not able to be reduced anymore due they can produce negative effects in the function of the chips (basically because the electrons produce can work outside of it´s orbits-“tunnel effect”) the quantum computing was develop to solve this problem using the laws of quantum mechanics,so the particle could be superposed which allows several operations at a time. A qubit has two types of states: convencionally |0> and |1> (ket cero and ket one) and the qubital. Conclution: Quatum computers have a superior level of calculation due the status of qubits. Qubits can experiment an entanglement, which allows a superposition of different simultaneous binaries chains

<span style="color: #eb55f6; font-family: 'Comic Sans MS',cursive;">__Protons__: Protons are subatomic particles that has a positive charge. It´s found in the nucle us of every atom. It is made up of two smaller particles called quarks; two up quarks and one down quark. <span style="color: #eb55f6; font-family: 'Comic Sans MS',cursive;"> __Neutron:__ Neutrons are subatomic particles that has no electric charge, they are found in the nucleus, together with the proton, the number of the neutrons determines the isotopes of elements. __Electron:__ Electrons are also part of the subatomic particles of an atom, it has a negative charge. The number of electrns is determine by the number of protons in the nucleus.
